Description

Spray device for air purification of visible light catalytic nano-crystalline titanium

Technical Field

The utility model belongs to the technical field of air purification devices, and particularly relates to a spray device for air purification by visible light catalysis nanocrystalline titanium.

Background

With the improvement of living standard of people, the environment on which people live is polluted, industrial pollution, decoration pollution, automobile exhaust pollution and the like. Along with the bad gases such as formaldehyde, dust, haze, bacteria and the like, the invisible killers hidden by the people do not know when the harm can be fatal to the people. Nowadays, people's antifog haze consciousness reinforcing, to air quality more and more high, the electronic technology development is growing day by day, and air purifier is popular in the society. The existing air purification technology has a plurality of kinds, and the main technical means adopted comprises the following aspects:

1. the photocatalysis technology comprises the following steps: japanese scientists first discovered irradiated TiO₂The single crystal electrode can decompose water, and the photocatalysis technology is put into use in the 90 s of the 20 th century. When air and water pass through a photocatalyst material, the photocatalyst material is a technical unit, a large amount of hydroxide ions OH, peroxy hydroxyl radicals HO2, peroxide ions O2, hydroperoxide H2O2 and the like are generated through oxidation-reduction reaction, and the ions are diffused in the air, so that various organic compounds and partial inorganic matters are decomposed to remove harmful gas and peculiar smell by destroying cell membranes of bacteria, sterilizing and disinfecting proteins of coagulated viruses and the like. The photocatalytic sterilization mechanism which is proved by experiments is as follows: cell osmosis, coenzyme A destruction, endotoxin degradation, protein and lipid denaturation and decomposition, and cell mineralization. But conventional TiO₂And only depends on UVC ultraviolet catalysis. Currently, there are various air purifiers or sterilizing machines using ultraviolet rays for photocatalysis.

2. Quantitative active oxygen technology: active oxygen is a mature technology, has been used for more than one hundred years in the world, can quickly and thoroughly inactivate bacteria, and is one of the most environmentally-friendly, most thorough and effective purification modes internationally acknowledged when being reasonably used. Meanwhile, the strong oxidizing property of the catalyst enables the catalyst to react with carbonyl (carbon oxygen) and hydrocarbyl (hydrocarbon) compounds such as formaldehyde (HCHO) and benzene (C6H6) to generate CO₂、H2O、O₂Etc., thereby completely eliminating the above-mentioned harmful finishing residues. It is emphasized that the use of active oxygen must be controlled in concentration, which is subject to safety hazards. Currently more advanced purification on the marketThe device can accurately control the generation frequency of the active oxygen so as to control the concentration of the active oxygen.

3. Anion technology: the negative ion technology is also called as a unipolar ion flow technology, and the generated negative ion flow adsorbs suspended particles with positive charges in the air, so that the particles are continuously accumulated and become heavier, and are separated from an aerosol state and settled. The negative ions have a settling effect on particles with diameters between 0.001 and 100 microns but have a significant effect only on small-particle-size negative oxygen ions with high activity, which are called fine particles, namely PM2.5, for particles with diameters less than or equal to 2.5 microns. The anion air purifier makes the whole room full of anions by utilizing the characteristic of air diffusibility, can rapidly remove dust and fall dust without dead angles, and has a relatively thorough purification effect. Currently, there are many air purifiers or sterilizing machines developed using this technology on the market.

4. HEPA filter screen: five materials of PP filter paper, glass fiber, composite PPPET filter paper, melt-blown polyester non-woven fabric and melt-blown glass fiber are divided, particulate matters with specific particle sizes can be filtered, and the filter paper is widely applied to air purifiers or air disinfectors. The disadvantage is that after a period of use, the filter screen becomes clogged and must be replaced.

5. Activated carbon: the active carbon is prepared by taking carbon-containing substances such as wood chips, shells, lignite and the like as raw materials and carbonizing and activating the raw materials. The particle size of the powder is 10-50 microns, and the particle size of the powder is 0.4-2.4 mm. The general property is porous and the specific surface area is large. The total surface area reaches 500 ~ 1000 per gram square meters, and the purification effect and the aperture size of active carbon are directly relevant, and the purification effect is most obvious when the aperture size is close to the particulate matter diameter, and coconut fiber charcoal is a neotype active carbon, and the less purifying effect of its aperture size ratio diameter is more obvious, is used widely in air purifier or air sterilizing machine etc.. The disadvantage is that after a period of use, it must be replaced.

6. Purifying plants: it is common to have tens of plants such as scindapsus aureus, begonia, chrysanthemum, chlorophytum comosum and anthurium andraeanum. The disadvantage is that the purification efficiency is not high.

7. Grafting high polymer polymerization technology: the bad smell and pollution generating matter is adsorbed to the carrier and chemical reaction is generated to decompose the matter by changing the molecular structure of the matter to be treated, so as to reach the aim of powerful and fast deodorization and purification. The molecular weight is generally higher than 10 ten thousand, harmful air and peculiar smell molecules in the vehicle are strongly and rapidly adsorbed through the active macromolecular chain, and then target harmful substances are effectively eliminated through the decomposition reaction of the active functional groups. Organic substances and water are decomposed after the molecular structure of harmful air components is changed. No toxic side effect, safety and reliability. The adsorbed and decomposed substances are not released again after being treated. By the grafting coincidence technology of the molecular structure, the grafted and grafted substance forms a stable high molecular polymer, thereby fundamentally solving the problem of lack of stability caused by the low molecular structure and avoiding the phenomenon of performance degradation of the product along with the time lapse. The adsorption and decomposition speed is high, the capacity is large, and the requirement on the use environment is low. This technique mainly is applicable to narrow and small airtight space such as car in, has to harmful air: formaldehyde, acetaldehyde, nonenal, lower fatty acids, acetic acid, isovaleric acid, basic malodorous substances, ammonia, amines, benzenes, toluene, xylene, other tvoc total volatiles, and the like. Especially eliminating carcinogens such as formaldehyde in the automobile, the effect is rapid and strong, and the molded products in the current market are not much.

8. Air disinfectant: most are colorless liquids with strong pungent odor. The air purifier is used for killing pathogenic microorganisms in the air to meet the harmless requirement, killing the pathogenic microorganisms outside the human body, cutting off the transmission path of infectious diseases and achieving the purpose of controlling the infectious diseases. The disinfectant can be divided into a sterilizing agent, a high-efficiency disinfectant, a middle-efficiency disinfectant and a low-efficiency disinfectant according to the action level. The sterilizing agent can kill all microorganisms to meet the sterilization requirement, and comprises potassium permanganate, formaldehyde, glutaraldehyde, ethylene oxide, peroxyacetic acid, hydrogen peroxide, chlorine dioxide and the like. Its advantages are high speed and efficiency, strong irritant smell, secondary environmental pollution and no durability.

In view of the above, the present invention is particularly proposed.
